以葡萄糖为前驱物,采用水热法合成了胶态碳球,然后利用胶态碳球制备了Co3O4/CoO/Co/石墨复合材料.此复合材料与其它研究者采用类似方法制备的物质相比具有完全不同的结构,它们是由多层不同物质组成的球形结构,其最外层是Co3O4,第二层是CoO,第三层是Co,最里面一层是石墨.采用循环伏安和恒电流充放电等方法对Co3O4/CoO/Co/石墨的电化学性能进行了测试.研究表明:该材料的电容行为是由氧化还原反应所产生的法拉第赝电容和双电层电容组成,其比电容为25.2 F g-1,比纯Co3O4的低,但电势窗口为-1.0～0.46 V,比纯Co3O4的大. Co3O4 / CoO / Co / graphite composites were prepared by using colloidal carbon spheres, using glucose as precursor and hydrothermal method to synthesize colloidal carbon spheres. Compared with other materials prepared by other researchers using similar methods They have completely different structures, which are spherical structures composed of multiple layers of different materials, the outermost layer is Co3O4, the second layer is CoO, the third layer is Co, and the innermost layer is graphite.Using cyclic voltammetry and constant The electrochemical performance of Co3O4 / CoO / Co / graphite was tested by current charging and discharging.The results show that the capacitive behavior of the material is composed of Faraday pseudocapacitance and electric double layer capacitance generated by redox reaction, and its specific capacitance Is 25.2 F g-1, lower than that of pure Co3O4, but the potential window is -1.0 ~ 0.46 V, which is larger than pure Co3O4.
